Size and weight is a big decision factor when you are trying to find the ideal camera for your needs.
In this section, We are going to illustrate Panasonic G9 and Nikon L840 side-by-side from the front, back and top in their relative dimensions. Panasonic G9 has external dimensions of 137 x 97 x 92 mm (5.39 x 3.82 x 3.62″) and weighs 658 g (1.45 lb / 23.21 oz) (including batteries). Nikon L840 has external dimensions of 114 x 89 x 96 mm (4.49 x 3.5 x 3.78″) and weighs 538 g (1.19 lb / 18.98 oz) (including batteries).
Below you can see the front view size comparison of Panasonic G9 and Nikon L840. Nikon L840 is 23mm narrower and 8mm shorter than Panasonic G9 but it is also 4mm thicker. As you can tell, actually this is not a fair size comparison since Nikon L840 has a built-in lens but Panasonic G9 doesn't. Once you put a lens on G9, its thickness will increase significantly.
Here is the back view size comparison of Panasonic G9 and Nikon L840.
Now lets look at the top view comparison of Panasonic G9 and Nikon L840.
Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Nikon L840 is significantly lighter (120g ) than the Panasonic G9 which may become a big advantage especially on long walking trips.
Again, this comparison may not be very useful in real life as we are comparing the weight of a camera with a built-in lens to the body-only weight of an interchangeable lens camera. Once you put a lens on G9, the total kit will weigh much higher.
With its weather sealed body, we believe that G9 has a big advantage over L840 which doesn't provide any kind of environmental sealing.
LCD Screen Size and Features
Panasonic G9 and Nikon L840's LCD screens has the same diagonal size of 3.00".
Nikon L840 features a Tilting only screen
which is mostly only good for shooting from waist or over the head levels. On the other hand, Panasonic G9 sports a Fully Articulated screen
which is more flexible and useful especially for taking Selfie shots and video.
